1. What animals do we have? Can you identify them? Can you locate where they are found - map?
2. Are any of them siginficant - rare, endangered, used by indigenous Australians as food or for clothing etc?
3. Can you correlate location with habitat types? Does the management of the vegetation influence the way that you will need to manage the animals?
4. What management actions would you develop for their protection?
Jenna and Alice have take me water samples from the Watson Creek. Here is the when, what, how and why of what they did:.... Questions we raised:
How much water is available in the nature reserve? How wide/big are the bodies of water?
What are the oxygen levels of the water? Does this change in different areas?
What are the average temperatures of the bodies of water?
How much light is available in the water for plant life?
What is the salinity and pH of the water?
How clear is the water?
What dissolved minerals are found in the water?
Over the past 2 weeks samples were collected from different areas of one of the pond located in the Nature Reserve. The samples were taken from the Top of the pond, the Middle of the pond and the Bottom of the pond. Two samples were taken from each area from opposite sides of the pond to get a broader variety of samples from around the pond. There was also a small flow of water going into the pond from the side that appeared to have oil or some pollutant in it – two samples were taken from this flow as well. We measured turbidity, conductivity, temperature and pH levels – as well as the depth.

the average measurement of conductivity from the samples we took from the pond is 1619 µS/cm, fresh drinking water has an average conductivity of 100 µS/cm and some slightly salty drainage water found on salt affected farms will be around 1800 µS/cm. This means that the water in the pond at The Brian Henderson Nature Reserve has very slightly salty water that a variety of native animals can live in and drink from.
Darcy and Seyi we were only able to take one sample from each of the three ponds in the reserve. This is an insufficient sample size which doesn't give us broad enough results to make any conclusions about the frog life living in the reserve.
Here is a list of the reptiles around Victoria, and the habitats in which they live in.

Amphibians
Conservtion Status:
All of these frogs with the exception of the 'Growling Grass Frog' are labeled as 'Least Concern'. However The Growing Grass Frog is unfortunately endangered with no actual sightings of a fully mature Growling Grass Frog in the Reserve. We've caught and successfully identified several breeds of tadpole, including:
PobbleBonk
Spotted Marsh Frog
Sothern Brown Tree Frog
Striped Marsh Frog
However we do believe to have caught (and released!) 3 growling grass frog tadpoles which is exciting.
Reptiles and habitats.
Pygopus lepidiopus - Common Scaly-foot (Lizard) 1 Within the Melbourne area, the Common Scaly Foot is restricted to isolated populations on the Mornington Peninsula, where it lives on sandstone or in loose sand. It is usually most active in the hours immediately after dawn or immediately preceding dusk.
Amphibolurus muricatus - Jacky Lizard 12 Jacky Lizards are found throughout south-eastern Australia from South Australia to south-eastern Queensland.

You need to cross reference the possible animals on the Mornington Peninsula with the threatened list to suggest possible threatened species for this site. Field work to describe possible habitats on the school site and then to capture, identify and release individuals would be required.
Fish
Some infomation on some of the fish we have found Anguilla Australis(Short finned eel) We found this in the dam down near the gym. Mr Simpson said these are really hard to catch because they just go in and eat the fish that have been caught in the trap then they can easily get out again, so we were very lucky to catch it. This type of eel can grow up to 1m in length and weigh up to 3kg. These eels are very common throughout Victoria. If the eel is caught in clear water, they can provide good eating. Smoked eel has been found to be the most appetising. Short-finned eels are usually found where the water is still, for example lakes, swamps and dams, but they can also been found in rivers and streams, or where the water is of lower velocity.
Galaxias Maculatus(Common Galaxias) These fish are commonly 100 mm up to 190 mm in length. The Galaxias is common throughout Victoria. It tolerates a wide range of habitats but has a preference for still or slow moving waters. Able to withstand very high salinities well above that of sea water. This type of fish is not usually good to eat but is generally used for bait to catch different types of fish. Threatened species in victoria and infmation about them Agassiz’s chanda perch Silver Perch Grey nurse shark Great white shark Murray Hardyhead Unspecked hardyhead/non specked hardyhead Yarra pygmy Perch Barred Galaxias/brown galaxias Dwarf galaxias Cox’s Gudgen Empire Gudgen Australian Whitebait/tasmanian whitebait Trout cod Murray cod Macquarie perch Murray Darling Rainbowfish Southern Purple-spotted gudgeon Pale Mangrove Goby Variegated Pygmy Perch\ewens pigmy perch Australian Mudfish Freshwater Herring Australian Grayling Freshwater catfish Southern bluefin tune
Agassiz’s chanda perch Habitat Warm rivers, streams and billabongs and associated waters where there is plenty of weed cover. Brief Biology Known to reach 6.5 cm, Carnivorous, taking aquatic insects, and is reported as an avid feeder on mosquito larvae.
Silver Perch Habitat In rivers, large streams, lakes and impoundments, habitat associations range from upland river rapids, to sandy beaches in turbid lowland rivers. Silver perch is one of the only larger native fish to appear near the water surface. Brief History This species can grow up to 8 kg and 610 mm, however they more commonly reach 410 mm and 2.5 kg. Silver perch are omnivorous, with algae becoming increasingly important in the diet with age. They undertake long upstream migrations entirely within freshwater.
Trout cod – Habitat Cooler upper reaches of streams, usually in flowing pools between falls and rapids where the stream bottom is bed-rock, boulders and sand or gravel substrates. Larger fish are usually found in the deeper holes, smaller fish beneath and amongst boulders.
Brief Biology Trout cod spawn during spring-early summer when water temperatures are about 17-18°C, and are thought to breed at a smaller size than Murray cod. Eggs are adhesive and lay on or near the stream bottom. Diet includes aquatic insects and crustaceans such as yabbies, crayfish and shrimps. They may also leap from the water to take food items just above the surface.
Murray cod – Habitat Occurs most frequently in sluggish, turbid waters, usually in deep holes, where logs and stumps afford cover and provide spawning sites. Will live and breed in lakes if water conditions and habitat are suitable. Occurs naturally in upper reaches of the Murray-Darling system where the water is relatively clear and there is little fallen timber. Brief Biology Murray cod can attain 1.8 metres in length and 113.5 kg, and commonly reaches 55-65 cm and weights of 2-5 kg. Usually sexually mature at 4 years of age, growth is rapid in the first 4-5 years, some individual fish reaching 64 cm in the fifth year. Spawning occurs in the spring and summer months in water temperatures between 16 and 21°C. Females can lay up to 40,000 eggs which are deposited in hollow logs or shallow water. Eggs hatch 6 to 13 days later, with juvenile fish feeding freely about 3-4 weeks later. Carnivorous, taking a wide variety of food from molluscs and crustaceans to many species of fish, and occasionally water birds such as ducks.
Macquarie perch – Habitat Naturally a riverine fish, preferring deep holes. Cool, upper reaches of Victorian tributaries of the Murray-Darling system. Does well in impoundments with suitable spawning streams (Victoria's best population is in Lake Dartmouth where this large lake is fed by suitable shallow spawning streams including the Mitta Mitta River). Brief Biology Can attain a weight of 3.5 kg, but more commonly in Victoria at a length of 35-40 cm and weights of 750 g-1 kg. Males can mature at 2 years of age and up to 21 cm; females at 3 years of age and up to 30 cm, although local conditions may induce the species to breed at smaller or larger sizes. Females of 30 cm or larger may produce between 50,000 and 110,000 eggs. Spawning usually occurs during spring or summer (October-January) with water temperatures between 16 and 22°C. Breeding occurs in flowing water where there are rock or gravel substrates. Eggs hatch after 10 to 18 days. Growth can be rapid, a five-year-old fish being 38 cm. Fish of 10 years of age have been collected. Carnivorous, taking its food by a sucking motion, principal diet items being aquatic insects with some crustaceans and molluscs.
Australian Grayling – Habitat River and streams with a cool, clear, moderate flow, with a gravel substrate and alternating pools and riffles. Brief Biology Known to reach 33cm in length, most common at 17-19cm. Believed to be omnivorous, taking insect larvae of various types, small crustaceans, and plant material. Matures sexually at 1-2 years of age and 15cm, females appear to mature after 2 years in fresh water, producing an average of 47,000 eggs. Complete life-cycle is not known, but current view is that spawning takes place in the freshwater mid-reaches of streams during late April-early May. Eggs are scattered over the substrate and newly hatched larvae are presumed to be swept downstream to brackish water where they remain for about 6 months. Newly-hatched fish are known to react strongly to light, preferring shady areas. During November juveniles ascend to the mid-reaches of the river where they spend the rest of their lives. Evidence indicates that the majority of grayling die before or during their third year.
Freshwater catfish- Habitat Variety of habitats, including lakes, rivers, creeks and billabongs, usually in sluggish or still water. Inhabits and spawns in flowing streams. Freshwater catfish prefer areas of sluggish or still water out of the current of the main channel. They are found in weedy areas on mud substrate and live and feed on the substrate. The adults are usually solitary fish whereas juveniles form loose schools. They appear to be sedentary fish with very limited movement along the river. They are most active at night. Brief Biology Recorded to 90 cm in length and 6.8 kg in weight, individuals above 2 kg are uncommon. Essentially carnivorous bottom feeders, capable of exploiting a wide range of food sources. Crustaceans are the most important dietary item, followed by insects, snails and small fish. Water temperature between 20 and 24°C is considered the primary stimulus for spawning. Spawning involves construction of nests in sand or gravel by the male fish. If the nest is exposed by a drop in water level, another nest is built. If several nests are built and abandoned because of fluctuating water, spawning will not occur. Females deposit eggs, leaving the male to fan, clean and guard the nest for up to 2 weeks, although eggs usually hatch within 7 days. Nests have been observed to be used for several consecutive years, whether by the same or different pairs of fish is not known.
Barred Galaxias/brown galaxias – Habitat Small, shallow, gravel bottomed streams in mountainous areas, not yet colonised by trout. G. fuscus occupies an identical position in the stream ecology to small trout and is not found in waters that contain this introduced species. Trout directly compete with this species for living space and food. Prior to work by Victorian fisheries to construct barriers to upstream migration of trout (into waters inhabited with fuscus), surveys showed that the streams could be divided into three distinct zones. At the downstream end the streams held trout and no G. fuscus. At the upstream ends there were sections with fuscus and no trout. Between these two extremes was an "interface zone" where, as you moved higher in the stream to areas where less and less trout had so far penetrated, there were progressively more fuscus. Examination of the gut contents of trout from this zone found that G. fuscus were being heavily predated. Clearly, as the trout were migrating into these areas, they were exterminating the galaxias
Murray Hardyhead – Habitat Variety of habitats including slow-flowing lowland streams, lakes, billabongs and swamps, most frequently in weedy areas or over gravel bottoms. Brief Biology Known to exceed 9 cm, but most commonly found up to 7 cm. Can withstand a wide range of salinities, up to 100,000 p.p.m., or three times that of sea-water. Little is known of the life cycle, but ripe females have been collected from January to March. Believed to be omnivorous, taking both invertebrates and plant material.
Unspecked hardyhead/non specked hardyhead Habitat Found in a wide variety of habitats, including lagoons, swamps, lakes and slow-flowing reaches of river and creeks, usually in shallow, vegetated areas, but it may congregate where streams flow into still water. Brief Biology Known to reach 10 cm. Able to adapt to water temperatures from 9 to 28oC, and salinities between 3,000 and 9,000 p.p.m. Breeding season, from October to mid February. Eggs are laid at random over rocks, crevices and gravel.
Yarra pygmy Perch – Habitat Frequents weedy slow-flowing or still waters such as lakes, dams, billabongs and irrigation channels, or the slow-flowing areas of stream edges where aquatic vegetation is present in small creeks and backwaters of larger rivers. Brief Biology Known to attain more than 8 cm, it seldom exceeds 6.5 cm. Breeding season is September-October when water temperatures reach 16 to 21oC. Females can lay between 500 and 4,000 eggs, which are scattered randomly over the bottom, adhering to rocks and vegetation. Observation suggest that females may spawn several times during a season. Males defend territory in which eggs are laid. Carnivorous, with major dietary items being insect larvae and small crustaceans.
Dwarf galaxias – It is a brilliantly coloured fish during the spawning period in particular and has an elaborate and fascinating spawning behaviour. It occurs only in waters south of the Divide and west of Lakes Entrance and occurs in at least 8 creeks on Mornington Peninsula. Adults reach 40 mm in length and prefer still water, often less than 30 cm deep with abundant aquatic vegetation. Juvenile fish congregate in schools of about 20 fish on the surface of pools.
At spawning time the female only lays a few (10) eggs each day for up to two weeks placing each egg carefully on vegetation. Populations can survive in areas that partially or completely dry up during summer. It appears likely that they can bury themselves beneath rocks or logs as the water recedes and survive until water level rises again. This process is called aestivation.
They can also travel overland between swamps and ponds providing there is a thin layer of moving water at least 2mm deep. This explains why they occur in swamps or isolated ponds, some distance from rivers. Their survival depends on retaining areas of shallow, still water. They are most common in the La Trobe River Basin, Bunyip River Basin and the upper reaches of the Glenelg River Basin.
Cox’s gudgeon – Habitat Appear to be more abundant in flowing waters, including rapids. Adults are not often found in lower reaches of streams, but individuals have been found upstream at altitudes of 700m. Brief Biology Can reach 19 cm in length, but most common to 15 cm. Spawning involves laying eggs on rocks, with the male fish remaining on guard and fanning the eggs, which hatch after only a few days. As large numbers of juveniles are found in middle and lower reaches of streams it is thought that young fish are washed downstream to later migrate upstream. Carnivorous, feeding mainly on small aquatic insects including mosquito larvae.
Southern Purple-spotted gudgeon – Habitat Most frequently found in slow-flowing or still waters including rivers, creeks and billabongs, near cover such as rocks, logs and aquatic plants. Brief Biology Known to reach 14 cm, but most commonly found to 7 cm. Spawning season is between December and February, with the eggs being laid in a single cluster on a solid substrate, sometimes very close to the water surface on the underside of floating vegetation. Females produce between 300 and 1,300 eggs which the male guards and fans. Individual females may spawn several times over a season. Carnivorous; diet includes worms, insect larvae, small crustaceans and mosquito fish.
Pale Mangrove Goby – Habitat Normally found in mangroves or holes in sea grass areas, sometimes entering freshwater. Brief Biology A hardy species able to tolerate high water temperatures and a wide salinity range. Grows to a length of 6 cm. Variegated Pygmy Perch\ewens pigmy perch – Habitat Small shallow creeks, fast flowing with abundant aquatic vegetation. Seems to have a preference for well-oxygenated streams. Brief Biology As for Nannoperca australis. Maximum size 7 cm, little is yet known of its biology.

Habitat
Warm rivers, streams and billabongs and associated waters where there is plenty of weed cover.
Brief Biology
Known to reach 6.5 cm, Carnivorous, taking aquatic insects, and is reported as an avid feeder on mosquito larvae.
Silver Perch
Habitat
In rivers, large streams, lakes and impoundments, habitat associations range from upland river rapids, to sandy beaches in turbid lowland rivers. Silver perch is one of the only larger native fish to appear near the water surface.
Brief History
This species can grow up to 8 kg and 610 mm, however they more commonly reach 410 mm and 2.5 kg. Silver perch are omnivorous, with algae becoming increasingly important in the diet with age. They undertake long upstream migrations entirely within freshwater.
Trout cod –
Habitat
Cooler upper reaches of streams, usually in flowing pools between falls and rapids where the stream bottom is bed-rock, boulders and sand or gravel substrates. Larger fish are usually found in the deeper holes, smaller fish beneath and amongst boulders.
Brief Biology
Trout cod spawn during spring-early summer when water temperatures are about 17-18°C, and are thought to breed at a smaller size than Murray cod. Eggs are adhesive and lay on or near the stream bottom.
Diet includes aquatic insects and crustaceans such as yabbies, crayfish and shrimps. They may also leap from the water to take food items just above the surface.
Murray cod –
Habitat
Occurs most frequently in sluggish, turbid waters, usually in deep holes, where logs and stumps afford cover and provide spawning sites. Will live and breed in lakes if water conditions and habitat are suitable. Occurs naturally in upper reaches of the Murray-Darling system where the water is relatively clear and there is little fallen timber.
Brief Biology
Murray cod can attain 1.8 metres in length and 113.5 kg, and commonly reaches 55-65 cm and weights of 2-5 kg. Usually sexually mature at 4 years of age, growth is rapid in the first 4-5 years, some individual fish reaching 64 cm in the fifth year.
Spawning occurs in the spring and summer months in water temperatures between 16 and 21°C. Females can lay up to 40,000 eggs which are deposited in hollow logs or shallow water. Eggs hatch 6 to 13 days later, with juvenile fish feeding freely about 3-4 weeks later.
Carnivorous, taking a wide variety of food from molluscs and crustaceans to many species of fish, and occasionally water birds such as ducks.
Macquarie perch –
Habitat
Naturally a riverine fish, preferring deep holes. Cool, upper reaches of Victorian tributaries of the Murray-Darling system. Does well in impoundments with suitable spawning streams (Victoria's best population is in Lake Dartmouth where this large lake is fed by suitable shallow spawning streams including the Mitta Mitta River).
Brief Biology
Can attain a weight of 3.5 kg, but more commonly in Victoria at a length of 35-40 cm and weights of 750 g-1 kg. Males can mature at 2 years of age and up to 21 cm; females at 3 years of age and up to 30 cm, although local conditions may induce the species to breed at smaller or larger sizes.
Females of 30 cm or larger may produce between 50,000 and 110,000 eggs. Spawning usually occurs during spring or summer (October-January) with water temperatures between 16 and 22°C. Breeding occurs in flowing water where there are rock or gravel substrates. Eggs hatch after 10 to 18 days. Growth can be rapid, a five-year-old fish being 38 cm. Fish of 10 years of age have been collected. Carnivorous, taking its food by a sucking motion, principal diet items being aquatic insects with some crustaceans and molluscs.
Australian Grayling –
Habitat
River and streams with a cool, clear, moderate flow, with a gravel substrate and alternating pools and riffles.
Brief Biology
Known to reach 33cm in length, most common at 17-19cm. Believed to be omnivorous, taking insect larvae of various types, small crustaceans, and plant material. Matures sexually at 1-2 years of age and 15cm, females appear to mature after 2 years in fresh water, producing an average of 47,000 eggs.
Complete life-cycle is not known, but current view is that spawning takes place in the freshwater mid-reaches of streams during late April-early May. Eggs are scattered over the substrate and newly hatched larvae are presumed to be swept downstream to brackish water where they remain for about 6 months.
Newly-hatched fish are known to react strongly to light, preferring shady areas.
During November juveniles ascend to the mid-reaches of the river where they spend the rest of their lives. Evidence indicates that the majority of grayling die before or during their third year.
Freshwater catfish-
Habitat
Variety of habitats, including lakes, rivers, creeks and billabongs, usually in sluggish or still water. Inhabits and spawns in flowing streams.
Freshwater catfish prefer areas of sluggish or still water out of the current of the main channel. They are found in weedy areas on mud substrate and live and feed on the substrate.
The adults are usually solitary fish whereas juveniles form loose schools. They appear to be sedentary fish with very limited movement along the river. They are most active at night.
Brief Biology
Recorded to 90 cm in length and 6.8 kg in weight, individuals above 2 kg are uncommon. Essentially carnivorous bottom feeders, capable of exploiting a wide range of food sources. Crustaceans are the most important dietary item, followed by insects, snails and small fish. Water temperature between 20 and 24°C is considered the primary stimulus for spawning. Spawning involves construction of nests in sand or gravel by the male fish.
If the nest is exposed by a drop in water level, another nest is built. If several nests are built and abandoned because of fluctuating water, spawning will not occur. Females deposit eggs, leaving the male to fan, clean and guard the nest for up to 2 weeks, although eggs usually hatch within 7 days. Nests have been observed to be used for several consecutive years, whether by the same or different pairs of fish is not known.
Barred Galaxias/brown galaxias –
Habitat
Small, shallow, gravel bottomed streams in mountainous areas, not yet colonised by trout. G. fuscus occupies an identical position in the stream ecology to small trout and is not found in waters that contain this introduced species. Trout directly compete with this species for living space and food.
Prior to work by Victorian fisheries to construct barriers to upstream migration of trout (into waters inhabited with fuscus), surveys showed that the streams could be divided into three distinct zones. At the downstream end the streams held trout and no G. fuscus. At the upstream ends there were sections with fuscus and no trout. Between these two extremes was an "interface zone" where, as you moved higher in the stream to areas where less and less trout had so far penetrated, there were progressively more fuscus. Examination of the gut contents of trout from this zone found that G. fuscus were being heavily predated. Clearly, as the trout were migrating into these areas, they were exterminating the galaxias
Murray Hardyhead –
Habitat
Variety of habitats including slow-flowing lowland streams, lakes, billabongs and swamps, most frequently in weedy areas or over gravel bottoms.
Brief Biology
Known to exceed 9 cm, but most commonly found up to 7 cm. Can withstand a wide range of salinities, up to 100,000 p.p.m., or three times that of sea-water. Little is known of the life cycle, but ripe females have been collected from January to March. Believed to be omnivorous, taking both invertebrates and plant material.
Unspecked hardyhead/non specked hardyhead
Habitat
Found in a wide variety of habitats, including lagoons, swamps, lakes and slow-flowing reaches of river and creeks, usually in shallow, vegetated areas, but it may congregate where streams flow into still water.
Brief Biology
Known to reach 10 cm. Able to adapt to water temperatures from 9 to 28oC, and salinities between 3,000 and 9,000 p.p.m. Breeding season, from October to mid February. Eggs are laid at random over rocks, crevices and gravel.
Yarra pygmy Perch –
Habitat
Frequents weedy slow-flowing or still waters such as lakes, dams, billabongs and irrigation channels, or the slow-flowing areas of stream edges where aquatic vegetation is present in small creeks and backwaters of larger rivers.
Brief Biology
Known to attain more than 8 cm, it seldom exceeds 6.5 cm. Breeding season is September-October when water temperatures reach 16 to 21oC. Females can lay between 500 and 4,000 eggs, which are scattered randomly over the bottom, adhering to rocks and vegetation. Observation suggest that females may spawn several times during a season. Males defend territory in which eggs are laid. Carnivorous, with major dietary items being insect larvae and small crustaceans.
Dwarf galaxias –
It is a brilliantly coloured fish during the spawning period in particular and has an elaborate and fascinating spawning behaviour. It occurs only in waters south of the Divide and west of Lakes Entrance and occurs in at least 8 creeks on Mornington Peninsula. Adults reach 40 mm in length and prefer still water, often less than 30 cm deep with abundant aquatic vegetation. Juvenile fish congregate in schools of about 20 fish on the surface of pools.
At spawning time the female only lays a few (10) eggs each day for up to two weeks placing each egg carefully on vegetation. Populations can survive in areas that partially or completely dry up during summer. It appears likely that they can bury themselves beneath rocks or logs as the water recedes and survive until water level rises again. This process is called aestivation.
They can also travel overland between swamps and ponds providing there is a thin layer of moving water at least 2mm deep. This explains why they occur in swamps or isolated ponds, some distance from rivers. Their survival depends on retaining areas of shallow, still water. They are most common in the La Trobe River Basin, Bunyip River Basin and the upper reaches of the Glenelg River Basin.
Cox’s gudgeon –
Habitat
Appear to be more abundant in flowing waters, including rapids. Adults are not often found in lower reaches of streams, but individuals have been found upstream at altitudes of 700m.
Brief Biology
Can reach 19 cm in length, but most common to 15 cm. Spawning involves laying eggs on rocks, with the male fish remaining on guard and fanning the eggs, which hatch after only a few days. As large numbers of juveniles are found in middle and lower reaches of streams it is thought that young fish are washed downstream to later migrate upstream. Carnivorous, feeding mainly on small aquatic insects including mosquito larvae.
Southern Purple-spotted gudgeon –
Habitat
Most frequently found in slow-flowing or still waters including rivers, creeks and billabongs, near cover such as rocks, logs and aquatic plants.
Brief Biology
Known to reach 14 cm, but most commonly found to 7 cm. Spawning season is between December and February, with the eggs being laid in a single cluster on a solid substrate, sometimes very close to the water surface on the underside of floating vegetation. Females produce between 300 and 1,300 eggs which the male guards and fans. Individual females may spawn several times over a season. Carnivorous; diet includes worms, insect larvae, small crustaceans and mosquito fish.
Pale Mangrove Goby –
Habitat
Normally found in mangroves or holes in sea grass areas, sometimes entering freshwater.
Brief Biology
A hardy species able to tolerate high water temperatures and a wide salinity range. Grows to a length of 6 cm.
Variegated Pygmy Perch\ewens pigmy perch –
Habitat
Small shallow creeks, fast flowing with abundant aquatic vegetation. Seems to have a preference for well-oxygenated streams.
Brief Biology
As for Nannoperca australis. Maximum size 7 cm, little is yet known of its biology.
